Issues
1) Does VI need a way to query for compatibility between a particular physical device (and queue family?) and a specific VI display?
RESOLVED: No. It is currently always assumed that the device and display will always be compatible.
2) VkViSurfaceCreateInfoNN::pWindow
is intended to store an
nn
::vi
::NativeWindowHandle
, but its declared type is a bare
void*
to store the window handle.
Why the discrepancy?
RESOLVED: It is for C compatibility.
The definition for the VI native window handle type is defined inside the
nn
::vi
C++ namespace.
This prevents its use in C source files.
nn
::vi
::NativeWindowHandle
is always defined to be
void*
, so this extension uses void*
to match.
